2.2 Operation of Modules
■Basic Operation of the Counter
The module incorporates a 16-bit ring up-counter to count the number of input pulses:
rising inputs from off to on, or falling inputs from on to off. The initial value of the counter is
0 (zero). The counter can count from $0 to $FFFF in hexadecimal. If the counter value
exceeds $FFFF, the counter will reset to 0.
Select a count edge of either rising or falling to count the number of input pulses (see the
input functions).
TIP
Note that a count value exceeding 32,767 in decimal numbers is expressed as a negative number.
■Setting the Ring Up-Counter Maximum Value
The counter has been set to count $0 to $FFFF in hexadecimal as a ring up-counter.
However, the maximum count value of the counter can be changed by setting bit 1 at the
input data set position and changing preset value 2 to an appropriate value. The ring up-
counter maximum set value is given by:
Ring up-counter maximum value = (preset value 2) – 1
In the above setting, if bit 0 is set, the ring up-counter maximum value will be $FFFF (see
the example below).
Example: When set value 2 is changed to 5, the ring up-counter is configured as follows:
Counter value changes: 0 to 1 to 2 to 3 to 4 to 0 to 1 to 2 to 3 to 4 to 0 to 1 to 2 to ......
The module detects a preset value when the counter value changes from 4 to 5, and
the counter will then reset to 0. This will configure a 0 to 4 ring up-counter.
When the counter is used as a variable ring up-counter, set the ring maximum value greater
than 20 (instead of set value 2). If the input pulse frequency is 1 kHz or lower, there is no
maximum set value limitation on preset value 2.
Input pulse frequency Preset value 2 for variable ring up-counter
0 Hz to 1 kHz No limitations on preset value 2
1 to 20 kHz Preset value 2 ≥20 TC0202.EPS
CAUTION
To change the ring up-counter maximum value, first stop the counter operation and then
reset it. If its maximum value is changed while the counter is operating, operation of the
counter will not be assured.

■Resetting the Counter
Resetting the counter means that the counter value returns to 0 (zero). Acounter value is
reset to 0 by setting the following or if the counter value exceeds its maximum set value.
(1) Resetting by output relays
Turning on (1) output relaysYuuu36,Yuuu40,Yuuu44, andYuuu48(slot
numbers for modules are entered in uuu) related to input channels 1 to 4 will reset
their related counter values.
(2) Counter value exceeds its maximum value
Acounter value is reset when it exceeds its maximum value.
■Counter Enabled and Disabled
Operation of the counter is enabled or disabled by setting the following:
(1) Enabling or disabling the counter by output relays
To set Counter Enabled or Disabled, use output relays Yuuu49, Yuuu53,
Yuuu57, and Yuuu61 (slot numbers for modules are entered in uuu) related to
input channels 1 to 4. While the output relay related to the input channel is off (0),
counter operation is disabled. While the output relay related to the input channel is on
(1), counter operation is enabled. Counter operation in the initial state after the power
is turned on is disabled (“stop counter operation”).
(2) Automatically stop the counter operation when the counter value is reset.
Operation of the counter will stop when the counter value exceeds its maximum value
and it is then reset. To stop the counter operation, set bit 1 rather than bit 2 at the data
position at which the corresponding input is set. When 0 is set for bit 2, counter
operation will continue.
To restart the counter operation, turn on the output relays related to the input channels 1 to
4(Yuuu35,Yuuu39,Yuuu43,andYuuu47).

<Toc> <Ind> <2. Functions and Operation > 2-7
IM 34M6H54-01E
■Comparing Counter Values with Preset Values
This module can provide two preset values (1 and 2) per input channel.
Counter values are always compared with these preset values.
• Equal (counter value = preset value)
• Counter value is smaller than the preset value (counter value < preset value)
• Counter value is equal to or greater than the preset value (counter value ≥preset
value)
These comparisons are applied to the input relays Xuuu01 to Xuuu31 (not including
Xuuu04, Xuuu08, Xuuu12, Xuuu16, Xuuu19, Xuuu20, Xuuu23, Xuuu24,
Xuuu27, and Xuuu28).
Input relays Xuuu01 to Xuuu15 (not including Xuuu04, Xuuu08, and Xuuu12) and
the corresponding external outputs will be off (0) if the related output relaysYuuu33
throughYuuu47 (not including Yuuu36,Yuuu40, and Yuuu44) change from off (0) to
on(1).
Preset value 2 is applicable as a maximum value of the ring up-counter.
The following gives an example of the coincidence of a counter value and the preset value.
When the set value is 0 (initial value):
The coincidence is detected when a counter value exceeds its maximum value and
returns to 0.
When $FFFF is set for the set value:
The coincidence is detected when the counter value exceeds $FFFE and then
reaches $FFFF.
TIP
The coincidence of a counter value with a preset value is detected when the counter value reaches the
preset value. However, when an output relay resets a counter value to 0 and the preset value is 0, or
when the set value has been changed to agree with the current counter value, the coincidence will not be
detected.
■Interrupts
An interrupt can be allowed in the following states:
(1) When the counter value and preset value 1 coincide;
(2) When the counter value and preset value 2 coincide; and
(3) When the counter value resets to 0 (zero).
This interrupt is allowed by declaring an interrupt.

IM 34M6H54-01E
■Output to External Output Terminal
The module incorporates four independent external output terminals to allow program-
mable setting of external outputs. Output setting can be made by:
(1) Output selection, and
(2) Interconnections between output and input channels.
(1) Output selection
Comparing the counter values with preset value 1 or 2 allows any output to be se-
lected from among eight latched outputs or status outputs, as well as counter operat-
ing states, “output normally on” and “output normally off.” In the initial state, latched
outputs, after the counter values have been compared with preset value 1, will be
selected.
The latched outputs are turned on when the counter value and preset value 1 or 2
coincide, or when the counter value exceeds a ring up-counter maximum value and is
reset. If a user’s program turns on a related output relay, the latched output will be off
(0). The latched output remains on until it is reset.
Astate output will be on when the comparison operation is true, and will be off when
the comparison operation is false.
The counter operating status indication output remains on (1) while the counter is in
operation, and remains off (0) while the counter is not in operation.
An output that is normally on or off remains on or off regardless of the counter operat-
ing status.
(2) Interconnections between input and output channels
Up to four remote output terminals can be set to output comparison results obtained in
a one-input channel. In the initial state, “output is issued to remote output terminals
n
relating to the input terminal n ” has been set. For example, comparison results in input
channel 1 are issued to remote output terminal 1.
Interconnecting between the input and output channels allows comparison results of
counter values in input channel 1 with preset values 1 and 2 to be output to four
remote output terminals. However, note that comparison results in input channels 2
through 4 cannot be issued to the remote output terminals.

■Input filter
If the module accepts dry-contact input pulses which may contain chattering noise, and the
counter counts these pulses, accurate counter values will not be obtained. To obtain a
correct counter value, use an input filter. Whether or not an input filter is used for each
channel can be set. Input filter constants are common to all input channels. For applica-
tions where the modules are used in a location with undesired electrical disturbance, set an
appropriate filter using application software.
